The Raspberry Pi Pico 1591B Relay Board is an all-in-one two-channel relay module and a power converter for the Raspberry Pi Pico and Pico W. This board allows the Pico to operate with 12V power and switch higher voltage / higher current devices from a compact, easy to mount, package.
The Pico 1591B Relay Board is compatible with both the Raspberry Pi Pico W and the standard Raspberry Pi Pico making it ideal for IoT applications or automation projects. The board uses GPIO pins 2 and 3 to control the two relays, but breaks out all additional pins in easy-to-access 0.100” / 2.54mm breadboard pitch through holes. To further extend functionality, we have also included a Qwiic / STEMMA QT connector, allowing any compatible breakout board or sensor to connect to the board.
The Pico 1591B Relay Board is designed to fit in a Hammond 1591BFLBK enclosure. Power is supplied through the two-pin screw terminal, while Common, Normally Open, and Normally Closed relay contacts are brought out for each of the relays in the 6 pin screw terminal. The Raspberry Pi Pico is connected using the castellated edges along the Pico, these are easily soldered with a conventional soldering iron. SMD Soldering Guide
